Service Procedure
1. Open the hood2. Disconnect the negative battery cable.
3. Disconnect the wiring harness on the crankshaft position sensor from the engine wiring harness.
NOTE:
The crankshaft position sensor connector is located on the passenger side of the engine compartment next to the transmission dipstick tube.
4. Remove the crankshaft position sensor connector and retaining clip from the retaining bracket
5. Raise the vehicle on an appropriate hoist.
6. Place a transmission jack under the transmission crossmember.
7. If equipped, remove the transfer case skid plate (Figure 1).
8. Remove the eight (8) transmission crossmember bolts (Figure 1).
9. Using the transmission jack, lower the rear of the transmission approximately three (3) inches.
10. Using a 7/16" (11 mm) swivel socket and a 36" long 3/8" drive extension, remove the crankshaft position sensor mounting bolt and wiring shield from the transmission bellhousing (Figure 2).
11. Remove and discard the old crankshaft position sensor.
12. Verify that the paper spacer is on the end of the new crankshaft position sensor (Figure 3).
13. Using electrical tape, tape the wiring shield to the sensor wiring conduit to hold the shield in position during sensor installation (Figure 4).
14. Position the new crankshaft position sensor into the transmission bellhousing and install the wiring shield and sensor mounting bolt finger tight (Figure 2).
15 Gently push the crankshaft position sensor until the paper spacer contacts the outer edge of the flywheel
16. While gently pushing the crankshaft position sensor against the flywheel, tighten the sensor mounting bolt to 60 in. lbs. (7 N.m).
NOTE:
The paper spacer is glued to the bottom of the crankshaft position sensor to correctly position the sensor from the flywheel. After the engine has been started the temporary paper spacer will be sheared off.
17. Route the crankshaft position sensor wiring along the top of the bellhousing
18. Using the transmission jack, raise the transmission back into position and install the transmission crossmember bolts. Tighten the crossmember bolts to 30 ft. lbs. (41 Nm) (Figure 1).
19. Remove the transmission jack from under the vehicle.
20. If equipped, install the transfer case skid plate. Tighten the bolts to 30 ft. lbs. (41 N.m) (Figure 1).
21. Lower the vehicle from the hoist.
22. Connect the crankshaft position sensor wiring pigtail to the engine wiring harness.
23. Install the crankshaft position sensor connector retaining clip to the retaining bracket.
24. Connect the negative battery cable.
